The first cam member 13 is integrally moved downward together with the support cylinder 12 of the tip member 9 of the contact arm 8, and the engagement between the cam surface 13a and the cam surface 15a of the second cam member 15 is released. In this state, the cam surface 13a of the height (length) to be set by rotating the first cam member 13 with respect to the support shaft 14 is selectively opposed to the cam surface 15a of the second cam member 15, and When the pushing-down operation on the support shaft 14 is released, the first cam member 13 is integrally moved upward together with the support cylinder 12 along with the upward movement of the support shaft 14 by the urging force of the first spring 17, and the cam surface 13a thereof moves to the first position. The cam surface 15a of the two-cam member 15 is opposed to the cam surface 15a. Here, the projection amount of the tip member 9 of the contact arm 8 with respect to the tip portion of the driver guide 4 is adjusted, and the tip member 9 is projected from the tip portion of the driver guide 4 for a long time in a shallow nailing state. Then, by engaging the high (long) cam surface 13a of the first cam member 13 with the cam surface 15a of the second cam member 15, the tip member 9 is also projected from the tip portion of the driver guide 4 for a short time. In the deep nailing state, the low (short) cam surface 13a of the first cam member 13 is engaged with the cam surface 15a of the second cam member 15 to adjust the settings to correspond to the nailing operation. The setting adjustment work is performed by rotating the first cam member 13, and the operation can be performed easily and easily, and the setting state can be adjusted by both cam surfaces 13a and 15a. The engagement is ensured.

Since the engaging recesses 12b and 12b are provided as recesses, the support shaft 14 is supported by engaging the support pin 14a of the support shaft 14 with the engaging recesses 12b and 12b of the support cylinder 12. It is possible to prevent the support shaft 14 from coming out of the support cylinder 12 by preventing the support shaft 14 from coming out upward from the support shaft 14 and rotating the support shaft 14 by approximately 90 degrees to position the support pin 14a in the notches 12a and 12a. Because it can be removed, The disassembling and assembling work of each member associated with the replacement of the tip member 9 of the arm 8 can be easily performed, and the parts of only the tip member 9 can be replaced.
【００１１】 以上詳述したように、本考案は釘打出し用のドライバの往復動によってドライ バガイド内に位置された釘を打出すとともに、該ドライバガイドに沿って配設さ れほぼ軸筒状の先端部材が同ドライバガイドの先端部位に位置されかつほぼアー ム状の末端部材が前記ドライバの往復動作を制御する部材に連繋されたコンタク トアームを備えた釘打機において、該コンタクトアームを前記先端部材側と前記 末端部材側と分割形成するとともに同部材間にドライバガイドに沿う軸方向の長 さを変化させるカム面を形成して該ドライバガイド先端部に対する先端部材の突 出長さを可変調整可能に構成したものであるから、コンタクトアームを構成する 先端部材と末端部材との間に介装したカム面を利用してドライバガイド先端部に 対する先端部材の突出長さを可変調整することができ、その操作がし易く、簡単 かつ確実に調整作業を遂行できる利点を発揮する。As described in detail above, according to the present invention, the nail positioned in the driver guide is driven by the reciprocating movement of the driver for driving the nail, and the nail is disposed along the driver guide and has a substantially cylindrical shape. In the nailing machine having a contact arm, the tip member of which is located at the tip portion of the driver guide, and the substantially arm-shaped end member is connected to the member for controlling the reciprocating movement of the driver. The tip member side and the end member side are formed separately, and a cam surface that changes the length in the axial direction along the driver guide is formed between the same members so that the protruding length of the tip member with respect to the tip end of the driver guide can be changed. Since it is configured to be adjustable, the cam surface interposed between the tip member and the end member that constitutes the contact arm is used to face the tip of the driver guide. The protruding length of the tip member can be variably adjusted, and the operation is easy, and the adjustment work can be performed easily and reliably.
